Figures of Earth by James Branch Cabell

But after dinner Dom Manuel came alone into the Room of Ageus, and equipped himself as the need was, and he climbed out of the charmed window for the last time. His final visit to the depths was horrible, they say, and they relate that of all the deeds of Dom Manuel's crowded lifetime the thing that he did on this day was the most grim. But he won through all, by virtue of his equipment and his fixed heart. So when Dom Manuel returned he clasped in his left hand a lock of fine straw-colored hair, and on both his hands was blood let from no human veins.

He looked back for the last time into the gray depths. A crowned girl rose beside him noiselessly, all white and red, and she clasped her bloodied lovely arms about him, and she drew him to her hacked young breasts, and she kissed him for the last time. Then her arms were loosed from about Dom Manuel, and she fell away from him, and was swallowed by the gray sweet-scented depths.
